AdcpXP - Acoustic Doppler Current Profiler Visualization

AdcpXP is a customized software developed at The University of Iowa's IIHR—Hydroscience & Engineering (IIHR). The software provides a wide range of flow characteristics derived from velocities measured by Acoustic Doppler Current Profilers (ADCP). In this initial stage, the software uses standard output files produced by Teledyne RD Instruments’ Rio Grande and StreamPro ADCPs ( AdcpXP is a stand-alone application fitted with graphical user interfaces that was developed with C++ and operates on Microsoft’s Windows platforms.

The software complements TD RDI’s WinRiver software that is primarily related to the estimation of stream discharges. AdcpXP brings in new visualization and post-processing capabilities to obtain additional flow characteristics enhancing the value of the measurements collected at fixed points or from moving vessels. The analysis can be conducted in a point, vertical, transect or at the reach scale. A summary of the AdcpXP capabilities is listed below.


Water Resources Engineering eBook

A Water Resources Engineering eBook has been posted as a series of PDF files by the Indian Institute of Technology (IIT) at Kharagpur. This is one in a series as part of an effort known as the National Programme on Technology Enhanced Learning (NPTel).

"The main objective of NPTEL program is to enhance the quality of engineering education in the country by developing curriculum based video and web courses. This is being carried out by seven IITs and IISc Bangalore as a collaborative project. In the first phase of the project, supplementary content for 129 web courses in engineering/science and humanities have been developed. Each course contains materials that can be covered in depth in 40 or more lecture hours. In addition, 110 courses have been developed in video format, with each course comprising of approximately 40 or more one-hour lectures. In the next phase other premier institutions are also likely to participate in content creation."

Visual AEM (Analytical Element Modeling)

Visual AEM was released a few months ago as the successor to Visual Bluebird. Visual AEM is "a graphical user interface for single and multi-layer analytic element modeling of (mostly) steady-state groundwater flow and numerical/analytical modeling of vertically-averaged contaminant transport". The application looks very much like Visual Bluebird, but does include several new features.

WaterCAST (the Water and Contaminant Analysis and Simulation Tool)

The Catchment Modelling Toolkit folks at eWater have released a development of their E2 modeling framework known as WaterCAST.

"The intent of WaterCAST is to provide managers of predominantly rural, and peri-urban, catchments with the capability to make informed decisions as to how changes in catchment management influence the quantity and quality of runoff to receiving waters. It is especially helpful for looking at water balance and for managing the factors affecting movement of sediments, nutrients and salts across catchments and in streams."

"WaterCAST differs from most catchment models in that it does not have a fixed structure and set of algorithms. It is actually a flexible framework that requires the user to consider and select a combination of models best suited to the problem at hand. So the user builds the specific modelling tool he or she wants according to the level of complexity appropriate to the problem and the available data and knowledge."


ANUGA Hydrodynamic Modeling

ANUGA Hydrodynamic Modeling is a software implementation of a hydrodynamic model which is specifically designed to model wetting and drying processes. ANUGA is a joint development project between Geoscience Australia (GA) and the Australian National University (ANU).

nofdp IDSS (nature-oriented flood damage prevention Information and Decision Support System)

The nofdp IDSS is an information and decision support system within the framework of the “nature oriented flood damage prevention” research and development project. The goal of the research and development project is to support integrative river basin management that takes regard of spatial planning, water management and ecology for small river catchment areas, especially to improve protection against flood damage.

The nofdp IDSS was developed cooperatively by Björnsen Consulting Engineers in Germany and Deltares in the Netherlands. This work was sponsored by EU funds from the Interreg III B Program. Project partners are:

* Hessian State Ministry for the Environment, Rural Development and Consumer Protection, Wiesbaden, Germany (lead partner)
* Darmstadt University of Technology, Darmstadt, Germany (project coordination)
* Province of Noord Brabant, ´s-Hertogenbosch, the Netherlands
* German Federal Institute of Hydrology, Koblenz, Germany
* Aa en Maas Water Board, ´s-Hertogenbosch, the Netherlands
* Brabantse Delta Water Board, Breda, the Netherlands
* De Dommel Water Board, Boxtel, the Netherlands
* Mümling Water Board, Erbach, Germany


Note on CDM version of SWMM5

On the CDM version of SWMM5, Robert Dickinson informs me: "This version is a QA/QC version of SWMM 5 that was used to more closely compare the SWMM 4 to SWMM 5 results using extra data variables. It should not be used for modeling."

NRCS Stream Restoration Design Handbook

Part 654 (Chapter 14) Stream Restoration Design of the National Engineering Handbook

Over 200 practitioners from government, private, and academic fields participated in the development of Part 654 (Chapter 14) Stream Restoration Design of the National Engineering Handbook (NEH). National Engineering Handbook Part 654 focuses on design tools for stream restoration projects.

Copies are available free of charge on CD from LANDCARE or by calling 1-888-LANDCARE (e-mail: The handbook can also be downloaded from the NRCS Directives Website.
