a considerable part of precipitation falls in the form of snow in golestan watershed. in turn, snowmelt plays a significant role in surface runoff, groundwater feeding and flood propagation in this area. snow cover area (sca) as an indicator of stored water can be implemented for temporal and spatial monitoring of snowmelt in the hydrological models. to monitor spatial and temporal variation of...

Daily, or more frequent, maps of surface water have important applications in environmental and water resource management. In particular, surface water maps derived from remote sensing imagery play a useful role in the derivation of spatial inundation patterns over time. MODIS data provide the most realistic means to achieve this since they are daily, although they are often limited by cloud co...

New technologies promise reduced flash flood losses. However, real-time observations with vast multi-sensor networks, more precise mapping capabilities using remote sensing and GIS, quicker hydrological and meteorological models, and increasing forecast lead times have not reduced losses. In November, 1999, 35 researchers from nine countries met in Ravello, Italy at a NATO sponsored Advanced St...

Distributed Server Programming using .Net and ArcObjects Track: Application Development Author(s): Brian Flood This paper explores the use of both .Net and ArcObjects in the Programmable Mapping Cluster (PMC), a software framework to ease ArcObjects development over large groups of servers. The PMC makes extensive use of the .Net Remoting architecture to connect all servers in a cluster into a ...

Abstract. In this communication, we present the exposure of agricultural lands to flooding caused by extreme precipitation in western Europe from 12 15 July 2021. Overlaying flood inundation maps derived near-real-time RAdar-Produced Inundation Diary (RAPID) system on Coordination information environment (CORINE) Land Cover map estimate a 1920 km2 area affected flooding, with 64 % representing ...
