MIKE BASIN
|
|
Description
|
For addressing water allocation, conjunctive use, reservoir operation, or water quality issues,
MIKE BASIN couples the power of ArcView GIS with comprehensive hydrologic modeling to provide
basin-scale solutions.
The MIKE BASIN philosophy is to keep modeling simple and intuitive, yet provide in-depth insight
for planning and management. In MIKE BASIN, the emphasis is on powerful simulation result
visualization in both space and time, making it the perfect tool for building understanding and
consensus.
For hydrologic simulations, MIKE BASIN builds on a network model in which branches represent
individual stream sections and the nodes represent confluences, diversions, reservoirs, or water
users. The ArcView GIS interface has been expanded accordingly, e.g., such that the network
elements can be edited by simple right-clicking. Technically, MIKE BASIN is a quasi-steady-state
mass balance model, however, allowing for routed river flows. The water quality solution assumes
purely advective transport; decay during transport can be modeled. The groundwater description uses
the linear reservoir equation.
|
|
Appropriate Use
|
Water availability analysis: conjunctive surface and groundwater use, optimization thereof.
Infrastructure planning: irrigation potential, reservoir performance, water supply capacity, waste
water treatment requirements. Analysis of multisectoral demands: domestic, industry, agriculture,
hydropower, navigation, recreation, ecological, finding equitable trade-offs. Ecosystem studies:
water quality, minimum discharge requirements, sustainable yield, effects of global change.
Regulation: water rights, priorities, water quality compliance.
|
|
Scope
|
Surface- and groundwater systems; national or site-specific.
|
|
Key Output
|
Mass balances, detailed flow descriptions throughout the water system, water diversions, hydropower
generation, hydropower tradeoffs to other operating objectives. Water quality descriptions of
dissolved solids and water temperature.
|
|
Key Input
|
Overall system: Digitized river system layout, withdrawal and reservoir locations.
Water demand: Time series of water demand, percentage of ground abstraction, return flow ratio,
linear routing coefficient (irrigation only).
Water supply: Unit naturalized runoff (time series), initial groundwater elevation, linear reservoir
time constant, groundwater recharge time series.
Hydropower: time series of withdrawal for hydropower, installed effect, tail water level, machine
efficiency.
Reservoir: Initial water level, operational rule curves, stage-area-volume curve, time series of
rainfall and evaporation, linkages to users, priority of delivery, linkages to upstream nodes.
Water quality: rate parameters, temperature, non-point loads, weir constant for re-aeration,
transport time and water depth or Q-h relationship, concentrations in effluent.

Ease of Use
|
Relatively easy to use if user is familiar with ArcView software. Requires significant data
fordetailed analysis.
|
|
Training Required
|
Moderate training/experience in resource modeling required for effective use. Also requires working
knowledge of ESRI’s ArcView software.
|
|
Training Available
|
MIKE BASIN courses are arranged both regularly and upon request http://www.dhigroup.com/Software/WaterResources/MIKEBASIN.aspx.
|
|
Computer Requirements
|
ArcView 3.2 or 3.2a; Windows 98, NT, 2000, or XP operating system (MIKE BASIN may also run on Windows
