(Gassman et al., 2007), that can be accessed at https://swat.tamu.edu/publications/
(Comprehensive review of SWAT model article). Gassman et al (2014) provided description of the types of studies included, database structure, search options and other details for the database at that time (1,700 articles were indexed at that point

Pangio pathala Arjun & Sidharthan & Dahanukar & Raghavan 2022, new species
No full textPangio pathala, new species (Fig. 1) Holotype. KUFOS.FT.2020.1, 32.1 mm SL; India: Kerala: Thiruvanvandoor (9°20’23.09”N, 76°34’48.54”E), 7 m asl., coll. R. Sundar, A. Sidharthan & C. P. Arjun, 25 October 2020. Paratype. KUFOS.FT.2020.2 (c&s), 18.9 mm SL; same data as holotype; KUFOS.FT.2020.3, 22.3 mm SL; India: Kerala: Thiruvanvandoor (9°20’23.09”N, 76°34’48.54”E), 7 m asl., coll. R. Sundar, A. Sidharthan & C. P. Arjun, 11 November 2020. Diagnosis. Pangio pathala is distinguished from all other species of Pangio (except P. bhujia) by the absence of the dorsal fin (vs. presence), presence of four pectoral-fin rays (including an unbranched rudimentary ray) (vs. 5–11), 13 segmented (both branched and unbranched) caudal-fin rays (vs. 14–16), and a unique count of 27 caudal vertebrae (vs. 11–20), the highest among the known members of the genus. Pangio pathala is further distinguished from all other species of Pangio except P. bhujia, P. fusca, P. apoda, P. pulla and P. lidi by the absence of pelvic fins. Pangio pathala differs from its only subterranean congener, P. bhujia, in having four pectoral-fin rays (vs. three); five anal-fin rays (vs. six); greater number of vertebrae (67 vs. 62–63); and a raw genetic distance of 8.1–8.7% in the mitochondrial co1 gene. Description. Morphometric and meristic data are presented in Table 1. Body elongate, oval in cross section, strongly compressed laterally in caudal region.Standard length 14.2–18.2 times body depth; body depth 1.1–1.8 times body width. Caudal peduncle laterally compressed, long, its length 3.6–5.4 times its depth, its depth 2.4–4.4 times its width. Precaudal adipose keels well-developed, deep, long; dorsal adipose keel originating anterior to vertical from anal-fin origin; adipose keel of ventral profile originating immediately posterior to anal-fin base. Scales absent. Head rounded, small, about 10.5–13.1% SL. Eyes small, 4.8–6.5% HL. Mouth subterminal; with three pairs of elongated barbels. Two pairs of maxillary barbels, outer maxillary barbel reaching beyond posterior border of eye; inner maxillary barbel reaching between eye and nare. One pair of mandibular barbels, reaching anterior border of eye. Posterior margin of anterior naris developed into a long (47.53–58.61% HL), pointed flap, referred to as nasal barbel. Pectoral fin narrow, long, thread-like, with four rays including an unbranched rudimentary ray. Anal fin short with rounded margin, with one rudimentary ray followed by four unbranched rays. Pelvic fin and girdle absent. Dorsal fin and dorsal-fin pterygiophores absent. Caudal fin pointed, with both segmented and unsegmented, but unbranched rays: 4 dorsal unsegmented +6 dorsal segmented + 7 ventral segmented + 2 ventral unsegmented rays. Ribs on vertebrae 5–40. Total vertebrae 67 = 40 abdominal + 27 caudal vertebrae. Colouration. In life, body pinkish-red to light pink when freshly collected, becomes brownish pink in captivity, slightly darker on dorsal profile, ventral profile translucent. Eye a tiny small black spot. Caudal region translucent, rendering caudal vertebrae visible. Pectoral, anal, and caudal fins hyaline (Fig. 1a). In preservative, body pale yellowish-white with tiny black eye. Dorsal side of head and body with scattered minute melanophores only visible at 20× magnification. Distribution and habitat. Currently, Pangio pathala is known only from its type locality, Thiruvanvandoor, near the town of Chengannur, Kerala State, India (Fig. 2). Specimens were collected from an overhead water-storage tank connected to an old dug-out well using an electric water pump. The well is approximately 17 feet deep, and drawn water was used for drinking and household activities (Fig. 3). Etymology. The species name is based on the Sanskrit word pâtâla, which means ‘below the feet’, denoting the subterranean realms of the universe—which are located under the earth’s surface. A noun in apposition. Genetic analysis. In the maximum likelihood analysis based on the co1 gene, Pangio pathala and P. bhujia are sister species and form a clade with the other Western Ghats congeners (Fig. 4). Pangio pathala differs from P. bhujia by a raw genetic distance of 8.1–8.7%, and from all its other congeners for which genetic data (mitochondrial co1) are available, by a raw genetic distance of 14.4–19.5% (Table 2). New distribution record for Pangio bhujia. We also take this opportunity to record two specimens of P. bhujia from Indianoor (10°58’56.20”N, 76°2’32.51”E, 37 m. asl) near the town of Kottakkal. The two fish were collected from a shallow channel (<0.1 m depth) originating in a nearby pond (<2 m depth) used for irrigation. The substrate of the channel comprised of laterite soil covered by fallen, decayed leaves. The habitat is similar to the type locality of P. bhujia, which is located around 40 km north. Detailed morphological examination of the specimens, and comparison of its co1 gene sequence, confirmed its conspecificity with P. bhujia (Table 1 and Fig. 4). Co-occurring species in the channel and pond include Lepidocephalichthys thermalis, Pseudosphromenus cupanus, Rasbora dandia, Aplocheilus lineatus, and Puntius vittatus.Published as part of Arjun, C.

Implementation of Algorithm for Satellite-Derived Bathymetry using Open Source GIS and Evaluation for Tsunami Simulation
No full textAccurate and high resolution bathymetric data is a necessity for a wide range of coastal oceanographic research topics. Active sensing methods, such as ship-based soundings and Light Detection and Ranging (LiDAR), are expensive and time consuming solutions. Therefore, the significance of Satellite-Derived Bathymetry (SDB) has increased in the last ten years due to the availability of multi-constellation, multi-temporal, and multi-resolution remote sensing data as Open Data. Effective SDB algorithms have been proposed by many authors, but there is no ready-to-use software module available in the Geographical Information System (GIS) environment as yet. Hence, this study implements a Geographically Weighted Regression (GWR) based SDB workflow as a Geographic Resources Analysis Support System (GRASS) GIS module (i.image.bathymetry). Several case studies were carried out to examine the performance of the module in multi-constellation and multi-resolution satellite imageries for different study areas. The results indicate a strong correlation between SDB and reference depth. For instance, case study 1 (Puerto Rico, Northeastern Caribbean Sea) has shown an coefficient of determination (R2) of 0.98 and an Root Mean Square Error (RMSE) of 0.61 m, case study 2 (Iwate, Japan) has shown an R2 of 0.94 and an RMSE of 1.50 m, and case study 3 (Miyagi, Japan) has shown an R2 of 0.93 and an RMSE of 1.65 m. The reference depths were acquired by using LiDAR for case study 1 and an echo-sounder for case studies 2 and 3. Further, the estimated SDB has been used as one of the inputs for the Australian National University and Geoscience Australia (ANUGA) tsunami simulation model. The tsunami simulation results also show close agreement with post-tsunami survey data. The i.mage.bathymetry module developed as a part of this study is made available as an extension for the Open Source GRASS GIS to facilitate wide use and future improvements
