Real-time data from on-line sensors offer the possibility to update environmental simulation models in real-time. Information from on-line sensors concerning contaminant concentrations in groundwater allow for the real-time characterization and control of a contaminant plume. In this paper it is proposed to use the CPU-efficient Ensemble Kalman Filter (EnKF) method, a data assimilation algorithm, for jointly updating the flow and transport parameters (hydraulic conductivity and porosity) and state variables (piezometric head and concentration) of a groundwater flow and contaminant transport problem. A synthetic experiment is used to demonstrate the capability of the EnKF to estimate hydraulic conductivity and porosity by assimilating dynamic head and multiple concentration data in a transient flow and transport model. In this work the worth of hydraulic conductivity, porosity, piezometric head, and concentration data is analyzed in the context of aquifer characterization and prediction uncertainty reduction. The results indicate that the characterization of the hydraulic conductivity and porosity fields is continuously improved as more data are assimilated. Also, groundwater flow and mass transport predictions are improved as more and different types of data are assimilated. The beneficial impact of accounting for multiple concentration data is patent.

Wanxin Li, Harrie-Jan Hendricks Franssen, Philip Brunner, Zhi Li, Zhoufeng Wang, Yike Wang, Wenke Wang

Summary: Calculating actual bare soil evaporation based on potential evaporation is a widely used method in various disciplines. However, the impact of soil texture on potential evaporation is often overlooked. This study assessed the seasonal and diurnal variations of potential evaporation over different soil textures and found clear differences in evaporation rates. The differences can be explained by factors such as surface energy balance and thermal properties, which are influenced by soil texture.

Predicting discharge from a complex karst system using the ensemble smoother with multiple data assimilation

Alessandro Pansa, Ilaria Butera, J. Jaime Gomez-Hernandez, Bartolomeo Vigna

Summary: The ensemble smoother with multiple data assimilation can be used to predict discharge in an Alpine karst aquifer, specifically the Bossea aquifer. This method effectively fits a unit hydrograph along with other parameters in a hydrologic model, using observed discharge flow rates, daily precipitation, and temperatures. By analyzing multiple events, average models are defined for predicting flow discharge during spring and autumn, with acceptable results for the fall rainfall events. However, further exploration is needed for refining the snow melting approximation and the parameterization of the infiltration coefficient. Overall, the study concludes that the ensemble smoother can be used to characterize a karst aquifer for forecast analyses.

Isolating the effects of land use land cover change and inter-decadal climate variations on the water and energy cycles over India, 1981-2010

Nikhil Ghodichore, C. T. Dhanya, Harrie-Jan Hendricks Franssen

Summary: This study aims to assess the impacts of land use land cover change (LULCC) and inter-decadal climate variations (CV) on water and energy cycles in India. The results show that LULCC causes a decrease in evapotranspiration and soil moisture, while CV leads to an increase in evapotranspiration, soil moisture, and net radiation. The combined effect of LULCC and CV results in an overall increase in evapotranspiration.

Monitoring Irrigation in Small Orchards with Cosmic-Ray Neutron Sensors

Cosimo Brogi, Vassilios Pisinaras, Markus Koehli, Olga Dombrowski, Harrie-Jan Hendricks Franssen, Konstantinos Babakos, Anna Chatzi, Andreas Panagopoulos, Heye Reemt Bogena

Summary: Due to their unique characteristics, cosmic-ray neutron sensors (CRNSs) have the potential to monitor and inform irrigation management, optimizing water resource usage in agriculture. However, current practical methods for monitoring small, irrigated fields with CRNSs are unavailable, and the challenges of targeting areas smaller than the CRNS sensing volume remain unaddressed. This study uses CRNSs to continuously monitor soil moisture dynamics in two similar-sized irrigated apple orchards in Greece, and compares the CRNS-derived soil moisture with a reference obtained from a dense sensor network. An ad hoc calibration improved the accuracy of the CRNS-derived soil moisture before irrigation, but a correction based on neutron transport simulations and measurements from a non-irrigated location proved to be more effective in enhancing the CRNS-derived soil moisture, allowing for the monitoring of irrigation-induced soil moisture dynamics.

Experimental sandbox tracer tests to characterize a two-facies aquifer via an ensemble smoother

Valeria Todaro, Marco D'Oria, Andrea Zanini, J. Jaime Gomez-Hernandez, Maria Giovanna Tanda

Summary: Estimating aquifer properties and their spatial variability is a challenging task in groundwater flow and transport simulations. This study applies the ensemble smoother with multiple data assimilation method to infer the characteristics of a binary field using tracer test data. Two different approaches are compared, with the second one performing better by coupling the ensemble smoother with a truncated Gaussian model. Synthetic experiments are conducted to find the optimal configurations for real cases, and the results show that both the fully parameterized approach and the pilot point approach yield comparable solutions.
