runoff collect used for to minimize losses and strengthen water resources in watersheds.countries like some areas of iran are facing to water scarcity, faced with unsuitable distribution of rainfall. by expanding the use of water sources, using the principles of runoff from rainfall can be effective to solve the problem of water shortage.in order to estimate the runoff in watershedsthere are se...

Flood is one of the disasters that must be faced in lowlands with poor drainage system, when there high rainfall. Rainfall upstream River can affect water level downstream River. Calculation river discharge and forecast from time arrival flood Help prepare population to face disaster. That method used this lesson a quantitative analysis rainfall planned repatriate. Then, concentration (TC) befo...

[1] A study of the influences of interdecadal and interannual oceanic-atmospheric influences on April 1 Snow-Water Equivalent (SWE) in the western U.S. is presented. SWE data was identified at 323 Natural Resources Conservation Service (NRCS) SNOTEL (SNOwpack TELemetrysites) stations for the period of 1961 to 2004 and for 121 SNOTEL stations for the period 1941 to 2004. The phases (cold/negativ...

The main purpose of our work is to investigate the performance wave breaking and its effect on retrieval in data acquired from Chinese Gaofen-3 (GF-3) synthetic aperture radar (SAR) at C-band German TerraSAR-X (TS-X) X-band. SAR images available for this study included 140 GF-3 quad-polarization strip (QPS) mode 50 dual-polarized (vertical-vertical (VV) horizontal-horizontal (HH)) TS-X stripmap...

Abstract In this study, we analyzed the ocean surface wind speed dependence of off‐nadir data from Surface Waves Investigation and Monitoring (SWIM) aboard Chinese‐French Oceanography Satellite (CFOSAT). When were analyzed, SWIM normalized radar cross section (NRCS) at most incidence angles decreased along NCEP Global Forecast System speed. This trend is consistent with that in a Ku‐band geophy...

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and...
