DEPTH-AREA-DURATION ANALYSIS IN A KOREAN RIVER BASIN

Analysis of river sediments in the paleo- Meyghan basin

Introduction The territory of central Iran is now affected by the hot and dry climate. But, several evidences, such as the extreme erosion of running waters, huge alluvial fans, wide alluvial terraces, and flood deposits indicate colder and wetter climate in the territory (Ghahroodi Tali, 2011: 3). The rivers belong to the most important parts of the sedimentary basin. In fact, the rivers are...

A spatial analysis of phosphorus in the Mississippi river basin.

Phosphorus (P) in rivers in the Mississippi River basin (MRB) contributes to hypoxia in the Gulf of Mexico and impairs local water quality. We analyzed the spatial pattern of P in the MRB to determine the counties with the greatest January to June P riverine yields and the most critical factors related to this P loss. Using a database of P inputs and landscape characteristics from 1997 through ...

Investigation of Depth-Area-Duration Curves for Kurdistan Province

Determining Depth-Area-Duration (DAD) curves in drainage basins is one of the applied researches in hydrology. DAD curves exhibit the depth and the area covered by the rainfall with a particular duration. DAD analysis is widely used in characterization of precipitation extremes for specification of so-called design storms. In this study the DAD curves for the Kurdistan province were prepared an...

A general dimensionless rainfall depth-duration-ferquency relationship

Numerical Simulation of Groundwater Flow in a River Valley Basin in Jilin Urban Area, China

In order to evaluate the groundwater resources and aquifer system of the Jilin urban area (JUA), a groundwater numerical flow model was established by using the groundwater modeling system based on data from 190 boreholes. River stages were interpolated to control the groundwater flow field. The input parameters such as hydraulic conductivity and specific yield were based on data from 260 pumpi...
