A Physically Based Methodology for Regional Flood Frequency Analysis
The problem of flood frequency estimation in ungauged catchments is approached by using statistical procedures jointly with derived distribution techniques. The application of this methodology...

A National System for Threshold Runoff Estimation
Threshold runoff is the amount of effective (or excess) rainfall of a given duration uniformly distributed over a certain catchment that is just enough to cause flooding at the outlet...

Next Generation HEC Catchment Modeling
The Hydrologic Engineering Center (HEC) is developing next generation computer models to replace those in current use. The next generation Hydrologic Modeling System (HEC-HMS) is an object...

Design Flow Estimates for Catchments in El Dorado County, CA
A hydrologic model consisting of a rainfall-runoff model and a set of design storms is proposed for design flow calculation in El Dorado County, California. The rainfall-runoff model will...

Orange River—System Analysis
The Orange River drains the largest basin in Africa south of the Zambezi with a total catchment area of approximately 1 million km2. Due to the increasing...

Linear Pertubation Model: An Application to Tanzanian Catchments
Floods are still a problem to many countries in the world todate. Floods do cause damage to property and sometimes loss to human life. Flood control measures by structural and non-structural...

Research Needs for Debris Flow Disaster Prevention
A 'soft' disaster reduction strategy is proposed based on identification of hazard location, extent and maximum intensity; monitoring of antecedent catchment moisture, sediment and vegetation...

Contaminated Sediment Transport During Floods

Automated Delineation of Catchment Area Boundaries with TINs

Definition of a Weighting Function for Rainfall in Aggregated Rainfall-Runoff Models

Sediment Rating Curves Based on Ranked Values

Drainage Analysis Using Triangulated Irregular Networks

Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....

Station Selection for Pooling Flood Data in a Densely Gauged Region of the UK

Low Flow Index and Hydrogeological Characteristics
This work is set within a framework of research on drought phenomena, causes and effects, and the methods to fight the harmful effects of droughts in the agricultural, municipal and industrial...

Unification in Estimation of Confidence Intervals
One area of future development needs in technology pertaining to surface runoff hydrology is the unification of techniques used by govermental agencies in the estimation of surface runoff...

Overall Resistance Parameter of Flow Arising in the Catchment-Area of a Reservoir in Steep Land
On a small reservoir catchment in mountains, the basin storage S(t) during a flood was expressed in terms of the basin discharge Q(t) and the time-varying storage parameters K(t) and P(t),...
