Staggering amounts and varieties of information pour in from GIS and remote sensing systems every day, and this information must be collected, interpreted, and shared efficiently.
Hydroinformatics: Data Integrative Approaches in Computation, Analysis, and Modeling introduces the tools, approaches, and system considerations necessary to take full advantage of the abundant hydrological data available today. Linking hydrological science with computer engineering, networking, and database science, this book lays a pedagogical foundation in the concepts underlying developments in hydroinformatics.

It begins with an introduction to data representation through Unified Modeling Language UML , followed by digital libraries, metadata, the basics of data models, and Modelshed, a new hydrological data model. Building on this platform, the book discusses integrating and managing diverse data in large datasets, data communication issues such as XML and Grid computing, the basic principles of data processing and analysis including feature extraction and spatial registration, and modern methods of soft computing such as neural networks and genetic algorithms.
Today, hydrological data are increasingly rich, complex, and multidimensional. Providing a thorough compendium of techniques and methodologies, Hydroinformatics: Data Integrative Approaches in Computation, Analysis, and Modeling is the first reference to supply the tools necessary to confront these challenges successfully.

Excessive river sedimentation can cause extensive economic and ecological damage. Expensive dredging operations are needed to keep navigation channels clear and to maintain the capacity of water supply reservoirs. Deposition of fine Deposition of fine sediments in rivers can eliminate pool habitats, decrease embryo survival rates of certain fish, and affect macroinvertebrate density and diversity.
Sedimentation is often associated with anthropogenic watershed activities e. Effort has been spent on developing Best Management Practices BMPs to reduce the sediment loads caused by specific watershed activities.
Sediment monitoring networks have also been implemented to measure loads within streams and help determine the efficacy of BMPs over time. Yet, fundamental questions remain regarding how accurately loads can be estimated. Research suggests watershed hydrologic and geomorphic characteristics, sampling method and frequency, along with the method used to develop sediment-discharge rating curves can substantially affect the accuracy and precision at which sediment load estimates are made.
The confidence at which one can estimate sediment loads, based on a specific sampling protocol, is one of several important pieces of information that hydrologic observatories need to understand in order to help monitor load trends.
A computer program is being developed that allows one to estimate sediment loads using several sediment- discharge rating curves and bias correction factors. Using USGS mean daily sediment data for the Illinois River at Valley City, the program is employed to perform Monte Carlo simulations to predict confidence limits for loads estimated using different sampling protocols e.
Results of the different sampling approaches are compared. A discussion regarding how these results, combined with future simulations representative of different sediment monitoring locations, can help guide future monitoring efforts is provided.

The Illinois River is one of the The main goals of this study were to calculate annual average nitrate concentration and annual total loads in the Lower Illinois River and its tributaries for , and to determine how the selection of different approaches affects the calculated trends.
Discharge data concurrent with routine water quality samples were applied to a suite of approaches to estimate daily concentration and load for the period of analysis, including the seven-parameter regression equation along with several modeling residual adjustment techniques and the weighted regression on time, discharge, and season WRTDS method.
