H.H. Beltman: Natuursteencollecties deel 7
No full textDeel 6 over natuursteencollecties ging over de collectie ir. J.H. Beltman bij het Mineralogisch-Geologisch Museum (MGM) van de TU Delft en hoe deze collectie met 222 marmers terug te voeren valt op de steenhouwerij en machinale fabriek van marmerwerken H.H. Beltman uit Deventer. In deel 7 gaat universitair docent Heritage & Technology en natuursteenspecialist Wido Quist van de TU Delft dieper in op dit bedrijf aan de hand van een in 1907 opgemaakte inventaris van het hele bedrijf en ook op het tweede deel van de inventaris van de collectie.Heritage & Technolog
Feasibility of groundwater recharge dam projects in arid environments
No full textA new method for determining feasibility and prioritizing investments for agricultural and domestic recharge dams in arid regions is developed and presented. The method is based on identifying the factors affecting the decision making process and evaluating these factors, followed by determining the indices in a GIS-aided environment. Evaluated parameters include results from field surveys and site visits, land cover and soils data, precipitation data, runoff data and modeling, number of beneficiaries, domestic irrigation demand, reservoir objectives, demography, reservoirs yield and reliability, dam structures, construction costs, and operation and maintenance costs. Results of a case study on more than eighty proposed dams indicate that assessment of reliability, annualized cost-demand satisfied and yield is crucial prior to investment decision making in arid areas. Irrigation demand is the major influencing parameter on yield and reliability of recharge dams, even when only 3. months of the demand were included. Reliability of the proposed reservoirs as related to their standardized size and net inflow was found to increase with increasing yield. High priority dams were less than 4percent of the total, and less priority dams amounted to 23percent, with the remaining found to be not feasible. The results of this methodology and its application has proved effective in guiding stakeholders for defining most favorable sites for preliminary and detailed design studies and commissioning. © 2014.Adiat KAN, 2013, PURE APPL GEOPHYS, V170, P453, DOI 10.1007-s00024-012-0501-9; ALMUTTAIR FF, 1994, J WATER RES PL-ASCE, V120, P749, DOI 10.1061-(ASCE)0733-9496(1994)120:6(749); Al-Qurashi A, 2008, J HYDROL, V355, P91, DOI 10.1016-j.jhydrol.2008.03.022; Al-Turbak Abdulaziz S., 1989, INT J WATER RESOUR D, V5, P119, DOI 10.1080-07900628908722423; Andersen GR, 2001, J GEOTECH GEOENVIRON, V127, P335, DOI 10.1061-(ASCE)1090-0241(2001)127:4(335); Bartholome E, 2005, INT J REMOTE SENS, V26, P1959, DOI 10.1080-01431160412331291297; Chouinard L., 1996, J INFRASTRUCT SYST, DOI 10. 1061-(ASCE) 1076-0342(1996) 2: 1(23), 23-29; Department of Land Management, 1985, GEN SOIL MAP SAUD AR; Directorate of Projects Implementation, 2006, DAMS SAUD AR; Haimerl G., 2004, GROUNDWATER RECHARGE; Hydrology Division, 1983, HYDR PUBL, V98; Jarvis A, 2008, HOLE FILLED SEAMLESS; Koustoyiannis D., 2004, ENCY WATER; Lange J, 1999, WATER RESOUR RES, V35, P2161, DOI 10.1029-1999WR900038; Maidment D.R., 2002, ARC HYDRO GIS WATER; McIntyre N, 2009, ENVIRON MODELL SOFTW, V24, P726, DOI 10.1016-j.envsoft.2008.11.001; MICHAUD J, 1994, WATER RESOUR RES, V30, P593, DOI 10.1029-93WR03218; NASA, 2008, UMD LANDC CLASS; Natural Resources Conservation Service, 1997, NAT ENG HDB 630; PEGRAM GGS, 1980, J HYDROL, V47, P269, DOI 10.1016-0022-1694(80)90097-9; PILGRIM DH, 1988, HYDROLOG SCI J, V33, P379, DOI 10.1080-02626668809491261; Rijsberman FR, 2006, AGR WATER MANAGE, V80, P5, DOI 10.1016-j.agwat.2005.07.001; Saudi Geological Survey, 2008, HOW TO ORD; Shovic H.F., 2010, WATERSHED MANAGEMENT, P1094; Tizro A.T., 2007, J APPL SCI, V7; UNEP, 1997, WORLD ATLAS DESERTIF; U.S. Weather Bureau, 1958, TP 29 RAINF INT FREQ; Zakhem Boulos Abou, 2012, Hydrological Processes, V26, DOI 10.1002-hyp.84460
