A simulation was carried out in the Santa Catarina River watershed, located State of Nuevo Leon, Mexico, to study flood patterns and velocity maps during occurrence Hurricane Alex June-July 2010. To conduct this simulation, a two-dimensional model Watershed employed using HEC-RAS software. The driven by Multisensor grid precipitation data as input. Land cover soil layers were utilized order obt...

Fixing the ecological flow in world's rivers contributes to preservation of river ecosystems and management water resources, related social economic aspects; It is volume necessary maintain a healthy ecosystem capable providing goods services. The hydrological method was first proposed estimate flow, developed 60s 70s 20th century. There are different methods such as: hydrological, hydraulic, e...

computing or determining the amount of maximum flood debit in watershed is one of the main important parts of hydrological research in river improvement. in this regard it is necessary to be distinguished peak of flood flow and its hydrograph for favorable return period. this needs to have long time statistic and leminograph tools in study research area. in this study with the comparison of ava...

In this paper, we propose an extension for a model of unsaturated soils developed by Van Genuchten (1980) and obtain thermos-hydric to study the influence temperature on water retention curve. A brief presentation is described using independent parameter modeling method. The proposed hydrometric makes it possible predict, from experimental measurements carried out drainage-humidification paths ...

several empirical methods for flood flow rate estimation have been presented. in this study,eight new empirical runoff estimation method including dredge & burge, bourges, inglis, faning, hyderabad, burkli ziegler, cramar and possenti were calculated in bakhtegan watershed which is located in fars province. after studying empirical methods for annual flood flow rate estimation and comparing...

the necessity of using discharge data in hydrological designs and regional programming is an unavoidable matter. unfortunately, malfunctioning of observation instruments, natural disasters and other problems sometimes result in incomplete or missing data. having of data related to time series is necessary for every investigation about hydrometeorology. thus missing data should be estimated in a...
