- Computer Simulation Model for Flood Plain Development
This publication presents analytical progress in the development of a computer simulation model for flood plain development. A conceptual model was developed which includes the following five major parts: forecasting population and economic activities allocating activities to available land; integrating public policies restricting land use; measuring and projecting flood damages; and evaluating benefits based on appropriate formulas using flood damages reduced, land rents, and economic rent differences (locational advantages). Several concepts are introduced to solve problems associated with development of a simulation model including: a practical definition of the study area in conjunction with a dummy location; a two-level allocation for land use planning; the use of economic rent differences and equilibrium land rents in benefit measurement instead of only economic rents; and the use of cycles of relocations as an aid to orderly evaluation of benefits. - Computer Simulation Model for Floodplain Development, Part II: Model Description and Applications
This report presents a simulation model for the evaluation of national economic efficiency benefits of various levels of flood protection and alternative land use plans. The model has three major components: 1. Calculation of flood damages and economic rent components, 2. Allocation of land use requirements, 3. Benefit calculation based on location advantage and damage reduction. The report also presents the results of a test case in the Connecticut River Basin. - Corps of Engineers Harbor Projects: Development of Tools, Measures, and Organization of Data for Evaluating Performance; Volume III - User's manual IWR HARBORVU Version 1.1

This report describes the Ecological Dynamics Simulation Model - Light model (EDYS-L) in terms of its function and how to use the model software. EDYS-L is designed to mechanistically simulate complex ecological dynamics across spatial scales ranging from square meters to landscape and watershed levels. Modules include climatic simulators, hydrology, soil profile, nutrient and contaminant cycles, plant community dynamics, herbivory, animal dynamics, management activities, and natural/anthropogenic disturbances. Designation of scenarios and management alternatives for each simulation run is conducted within a Microsoft Windows user interface. Outputs include graphical displays in this interface, as well as extensive tabular files for all ecosystem components. - Evaluation of Interregional Input-Output Models for Potential Use in the McClellan-Kerr Arkansas River Multiple Purpose Project Impact Study

- Plan Formulation and Evaluation Studies - A Preliminary Analysis of Day Use Recreation and Benefit Estimation Models for Selected Reservoirs Volume III
This report presents a methodology for estimating recreation use and recreation benefits at existing and proposed Corps of Engineers reservoirs. It is the outgrowth of recreation use studies instituted by the Office of the Chief of Engineers, Washington, D.C. Multiple linear regression analysis is employed to develop two regional day use estimating models from recreation use survey data collected at 19 Corps reservoirs in the Fort Worth and Sacramento U.S. Army Engineer Districts. - Regional Economic Development Impact Model: Phase I Study, Final Report
A multiregional variable input-output (MRVIO) model is introduced to investigate the impact of a change in transportation costs on regional development and trade flows. The MRVIO model is a theoretically well-founded, practically useful, and policy-sensitive model. The regional technical coefficients and the trade coefficients are endogenous variables to the MRVIO model. These coefficients are sensitive to the transportation costs as well as other input costs. Each industry is assumed to have a linear logarithm production frontier with a constant return to scale. From the dual relation one can obtain the profit maximizing price frontiers. These prices are expressed in terms of transportation costs, wage rates, capital prices, input elasticities, and technical coefficients and the trade coefficients. Using the 1963 three-region, ten-sector interindustry flow data as a base, researchers investigated the impact of a change in transportation costs on trade structure, regional growth, and inflation. As expected, a decrease in transportation costs increases the input coefficients between the regions and decreases own trade coefficients; i.e., the purchases from other regions increase and the purchase from local markets decrease as the costs of transportation decrease. A decrease in transportation cost stimulates the regional development. However, its sensitivity differs among industries. - Regional Economic Development Models- A Critical Appraisal Based on the International Trade Experience

- Section 902 Analysis Certified Tool Manual
This is a manual that accompanies the Section 902 Certified Analysis Tool. Section 902 of the Water Resources Development Act (WRDA) of 1986 defines the maximum amount that a project may cost. This is often called the 902 Limit or Project Cost Cap. It is, "The maximum project cost limit imposed by Section 902 is a numerical value specified by law which must be computed in a legal manner (ER 1105-2-100 Appendix G)." - Short Guide on Interactive Decision Support Tools Using Microsoft(R) Excel
