Design Hydrographs in Coastal Wetland Watersheds
The use of synthetic unit-hydrographs for hydraulic design in ungaged watersheds has been an accepted practice for over 50 years. In southeastern U.S. coastal regions, which contain extremely...

Hydrology of Wetland Treatment Systems in East Orange County, Florida
Wetlands are increasingly being used as final treatment systems for industrial and domestic wastewater effluent discharges and stormwater runoff discharges. Hydrological monitoring and...

Hydrologic Runoff Models for the Arid Southwest United States
Recently, hydrologic study criteria manuals (or hydrology manuals) were prepared for the arid southwest regions of Clark County (Las Vegas vicinity, Nevada), Maricopa County (Phoenix vicinity,...

Lag Relations for Semi-Arid Regions and Urban Areas
The use of synthetic unit hydrographs often requires the estimation of lag or other travel time parameters. Several procedures are available for estimating such unit hydrograph parameters....

Flood Elevation Limits in the Rocky Mountains
An analysis of 77,987 station-years of streamflow-gaging station data from 3,748 stations in the Rocky Mountains indicates that there is a latitude-dependent elevation limit to substantial...

Lessons from Hurricane Andrew's Effects on Hydraulic Structures
Documentation and description of Andrew's effects on open channels and other hydraulic structures in South Dade County, Florida, are presented, based on observations made during field...

Linking Hydrologic and Hydraulic Routing Models in Low Relief Basins of South Florida
Combined use of hydrologic and hydraulic routing models to analyze the rainfall-runoff processes during a storm event is a common practice. In this approach, a hydrologic model is employed...

A Computer System to Operate Coastal Structures
The Central and Southern Florida Flood Control Project (C&SF) was designed and built by the U.S. Army Corps of Engineers and is operated and maintained by the South Florida Water...

Hydraulic Modeling of Alluvial Plains (Slopes) and Alluvial Fans Using DAMBRK
The design of hydraulic structures such as bridges on distributary flow areas and alluvial fans require methods that can adequately determine discharges at the structures. Flow conditions...

Alluvial Fan: Subset Definitions
The Flood Control District of Maricopa County, Arizona recently completed a study whose goal was to identify and describe four alluvial fans for instrumentation and long-term monitoring....

Flood Assessment at a Low-Level Radioactive Waste Site in Southern Nevada
Flood hazard analysis on alluvial fans using Federal Emergency Management Agency (FEMA) methodology is not limited to the FEMA Alluvial Fan Methodology (AFM). Other FEMA-accepted methods...

A GIS Application to Hydrology
This paper illustrates an application of Geographic Information System (GIS) in estimating input parameters for Penn State Runoff Model (PSRM), a watershed rainfall-runoff simulation model....

The Use of Geographic Information Systems and Models on Personal Computer and Workstation Platforms, in the Development of a Wellhead Protection Program, Salinas Valley, California
The Salinas Valley is located on California's Central Coast. The ground water basin supports 850,000,000 M2 of irrigated crops which have a market...

GIS Landscape?A Solution for Wellhead Protection
Wellhead protection is an emerging issue for water suppliers based largely on the 1986 Amendments to the Federal Safe Drinking Water Act (SDWA). State governments are developing wellhead...

Nonpoint Source Pollution Model for Agricultural and Rural Watersheds
A dynamic hydrologic and nonpoint source pollution simulation model for agricultural and rural watersheds; capable of simulating rainfall-runoff, soil erosion, sediment transport, mixing...

Evaluation of the Effects of Weather Modification to Enhance Reservoir Yield During Drought?Salinas Valley, California
Cloud seeding has been conducted for water years 1990-91 and 1991-92 in Monterey County, California in response to the extended drought. The Monterey County Water Resources Agency weather...

Development of a Raw Water Master Plan Model to Assist Long Range Drought and Water Conservation Planning for the City of Louisville, Colorado
The City of Louisville, a municipal corporation charged with meeting the water demands of almost 5,000 water accounts and faced with a diminishing supply of available senior water rights...

Lake-Level Declines in Karst Lake During Droughts
Lake-level declines in Brooklyn Lake, a karst lake in north-central Florida, have been investigated. Below average rainfall, vertical leakage to the underlying aquifer system, declining...

A Comparison of L-Moments with Method of Moments
A comparison of the Conventional Moments Method (CMM) with the L-Moments Method (LMM) for selecting a distribution is made. Five distributions GEV (Generalized Extreme Value), LNO (Lognormal),...

Lower Missouri River Water Quality Model for Evaluating Flow Alterations
A modified version of the US Environmental Protection Agency's (USEPA) one-dimensional (longitudinal) stream water quality model, QUAL2E, was applied to the lower Missouri River to evaluate...
