The Effects of Annual Storage and Random Potential Evapotranspiration on the One-dimensional Annual Water Balance
(Cambridge : Massachusetts Institute of Technology, Dept. of Civil Engineering, Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, 1980-02)An analysis is presented leading to the incorporation of storage terms into an existing first-order dynamic water balance. Annual change in storage in the unsaturated zone of an idealized soil column is included through ... -
Estimation of Effective Hydrologic Properties of Soils from Observations of Vegetation Density
(Cambridge, Mass. : Massachusetts Institute of Technology, Dept. of Civil Engineering, Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, 1980-03)An existing one-dimensional model of the annual water balance is reviewed. Slight improvements are made in the method of calculating the bare soil component of evaporation, and in the way surface retention is handled. A ... -
Time Series Analysis of Cyclostat Data for the Determination of Cell Division Patterns in Phytoplankton Grown on Light/Dark Cycles
(Cambridge : Massachusetts Institute of Technology, Dept. of Civil Engineering, Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, 1980)A method of data analysis employing digital filtering technique is described which has been used to smooth time series of cell density data from cyclostat experiments (Chisholm and Costello, 1980) and to estimate cell ...
