Enhancing the Evaporation Method for Accurately Determining Unsaturated Soil Properties in the Wet Range

B. Nam, B. Poudyal, V. Srinivasan, T. P. Clement

Journal of hydrologic engineering

volume 29, issue 6, December 2024, 04024038

DOI

https://doi.org/10.1061/JHYEFF.HEENG-6215

Highlights

  1. The evaporation method is widely used for determining soil water characteristic curve and unsaturated hydraulic conductivity
  2. However, the accuracy of the evporation method suffer in the wet range due to calibration offset errors in the tensiometer measurements.
  3. Here we propose an in-situ calibration method that corrects the offset errors in the tensiometer measurements.
  4. Our improved approach significantly extends the measuring range of the evaporation method.

Noise-induced errors in heat pulse-based sap flow measurement methods

S. Sogala Balaram, V. Srinivasan

Agricultural and Forest meteorology

volume 350, May 2024, 109988

DOI

https://doi.org/10.1016/j.agrformet.2024.109988

Highlights

  1. Most heat pulse-based sapflow models only use a few data points to estimate sapflow rates.
  2. When these data points are impacted by noise, the accuracy of these methods suffers.
  3. By using a sum of squares error minimization approach which uses all the measured data points errors due to noise in data can be virtually eliminated.
  4. The new approach significantly extends the measuring range of sapflow rates.

Stomatal conductance reduction tradeoffs in maize leaves: A theoretical study

A. Srivastava, V. Srinivasan, S. P. Long

Plant Cell and Environment

volume 47, issue 5, May 2024, pages 1716-1731

DOI

https://doi.org/10.1111/pce.14821

Highlights

  1. Current C4 crops such as maize are super-saturated with CO2 such that decreasing stomatal conductance does not affect photosynthesis but reduces water loss.
  2. Model simulations show that reducing maize stomatal conductance boosts water use efficiency (WUE) by up to 26% in upper leaves and 170% in lower leaves, with minimal photosynthesis impact.
  3. However, higher leaf temperatures due to reduced evaporative cooling could offset WUE gains by up to 16%.

Analytical solutions to three-dimensional reactive contaminant transport problems involving point, line, and area sources

J. Sangani, A. Srivastava, V. Srinivasan

Transport in Porous Media

volume 144, August 2022, pages 641-667

DOI

https://doi.org/10.1007/s11242-022-01828-x

Highlights

  1. 3D approximate analytical solutions are only available for contaminant sources emanating from a rectangular patch source with Dirichlet boundary conditions.
  2. New closed-form approximate solutions are developed for point, line, and area sources for both Dirichlet and Cauchy boundary conditions.
  3. Solution library facilitates the application of screening tools for a range of practically relevant simplified groundwater reactive contaminant transport problems.

Improved Domenico solution for three-dimensional contaminant transport

J. Sangani, V. Srinivasan

Journal of Contaminant Hydrology

volume 243, December 2021, 103897

DOI

https://doi.org/10.1016/j.jconhyd.2021.103897

Highlights

  1. Screening tools use approximate analytical solutions to model 3D contaminant transport.
  2. The approximate solution is erroneous under realistic longitudinal dispersivity values.
  3. An improved solution is derived using the characteristic residence time approach.
  4. Improved solution accounts for advective and dispersive effects in residence time.
  5. Easy to retrofit existing screening tools with the improved solutions for better accuracy.
