NUMERICAL MODELLING OF BRINE DISPERSION IN SHALLOW COASTAL WATERSIAEME Publication
Fresh water is a limited finite resource, vital for the existence of every life on earth. It is becoming a scarce commodity. This is due to population growth, climatic changes with more frequent extreme events such as droughts and floods, increased water contamination of existing supplies, inefficient use of water etc. To overcome this scarcity, creation of fresh water from sea water by the process of desalination is a effective and reliable way. Hence desalination plants are being widely used in coastal areas.
The river Bharathapuzha is the lifeline of three districts in Central Kerala namely Palakkad, Malappuram and Thrissur and also parts of Coimbatore district of Tamil Nadu. This region gets an increase in population during the recent years. Water is unevenly distributed as surface and groundwater resources. An integrated hydrogeological study in the whole basin has not been attempted so far. This is the result of our investigation.
Unit Hydrograph (UH) is the most famous and generally utilized technique for analysing and deriving flood hydrograph resulting from a known storm in a basin area. For ungauged catchments, unit hydrograph are derived using either regional unit hydrograph approach. Central Water Commission (CWC) derived the regional unit hydrograph relationships for different sub-zones of India relating to the various unit hydrograph parameters with some prominent physiographic characteristics. In this study, the lately developed UH model is applied located between Latitude 15º54′2′′ N to 16º16′19′′ N Latitude and 76º48′40′′ E to77º4′21′′ E Longitude. The study area covers an area of 466.02 km2, having maximum length of 36.5 km. The maximum and minimum elevation of the basin is 569 m and 341 m above MSL, respectively. The Peak discharge of unit hydrograph obtained is 171.58m3/s. The final cumulative discharge is 1669.05 m3/s.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. Seawater Intrusion
In coastal regions, overexploitation of groundwater has caused the
encroachment of seawater into freshwater aquifers.
Saltwater is heavier, hence tends to move underneath the freshwater layer.
The freshwater, however, has a hydraulic gradient downward towards the
coast, hence will flow to the sea.
This outflow momentum force can counter balance the density-driven
seawater.
Without it, seawater will continue to move inland until the entire aquifer
below sea level is occupied by it.
Since such a hydraulic gradient always exists due to the precipitation
recharge inland, an equilibrium position will establish. The toe then marks
the maximum extent of intrusion.
3. Seawater Intrusion in Coastal Area of North Goa
Coastal tracts of Goa (India) are rapidly being transformed into
settlement areas.
The poor water supply facilities have encouraged people to have
their own source of water by digging or boring a well.
During the last decade, there have been large-scale withdrawals
of groundwater by builders, hotels and other tourist
establishments.
Though the seawater intrusion has not yet assumed serious
magnitude, but in the coming years it may turn to be a major
problem if corrective measures are not initiated at this stage.
It is necessary to understand how fresh and salt water move
under various realistic pumping and recharge scenarios.
4. Objectives of the Study
• Simulation of seawater intrusion in a region along
Goa coast.
• Evaluation of the impact on seawater intrusion
due to various groundwater pumping scenarios.
• Sensitivity analysis to find the most sensitive
parameters affecting the simulation.
• Suggestions for remedial measures.

Dr. A. G. Chachadi (Goa University)
Duration: 3 Years (April 2004 to March 2007)
Budget: NIH Funding
6. Study Area
• The study area is bound by rivers Chapora and Mandovi in
north and south directions respectively, besides Arabian sea
in the west.
• Bardez Taluk of North Goa
(catchments of Baga & Nerul rivers = 74 km2)
• Coastal tract from Fort Aguada to Fort Chapora (15 km)
• One third tourists visit Bardez coastal areas
(Anjuna, Baga, Calangute beaches)
• Area of interest = 30 km2
7.
8. Work Plan:
• Establishment of technical collaboration with participating
agency (Goa University) and identification of a part of the
coastal area in Bardez taluk of North Goa for the present
study.
• Collection of relevant data, literature and maps.
• Field investigations:
Identification of 20 observation wells.
Measurement of monthly groundwater level data in
observation wells (September 2004 to August 2005).
Collection of groundwater samples in September,
November 2004, January, March, April, June 2005.
9.
10. Laboratory analysis:
Measurement of salinity for collected groundwater samples in
the laboratory.
Based upon the bi-monthly measurements of salinity,
groundwater quality in all the observation wells was found to be
reasonably fresh, both in pre- and post-monsoon periods.
It can be attributed to the fact that the transition zone of fresh
water-saline water lies below the shallow open wells, as evidenced by
vertical electrical soundings.
11. Resistivity Profiling and Sounding:
To know the distribution of salt-water/fresh-water
interface -
Resistivity profiling: Apparent electrical resistivity
measured along four profiles (Anjuna, Baga, Calangute
and Candolim) from sea coast to 525 meters inland.
Vertical electrical sounding: Carried out at 7 monitoring
well locations upto a depth of 20 metres.
Results of resistivity profiling and vertical electrical
sounding have been presented in forthcoming slides.

Result: The seawater mixed zone is witnessed along Anjuna and Baga beach
sections. Very close to the sea relatively higher apparent resistivity values
are due to dry sand dunes. However along Calangute and Candolim
beaches, there is no indication of seawater mixing at 10m depth.

Result: Well numbers 6, 7 and 8 show low values of resistivity below about 12 m
depth indicating the presence of seawater or mixed zone below this
depths. However, at other sites there is no indication of the seawater
mixing up to 20 m depth.

33. Presently, seawater intrusion in Bardez taluk of North Goa is confined only
upto 290 m from the coast under normal rainfall conditions and present draft
pattern. It may slightly extend farther for low rainfall years.
Seawater intrusion may further advance inland if withdrawals of
groundwater by builders, hotels and other tourist establishments continue to
increase in the coming years.
Groundwater salinity needs to be continuously monitored near the coastal
area, especially within 2 km from the coast.
Corrective measures with proper planning and management of groundwater
resources in the area need to be initiated so that it may not turn to be a major
water quality problem in the coming times.
